Hi,
I'd never heard of her till I saw your post, so I tried to find some info in terms of reviews or even something on the content of the book. The website is very flashy LOL and clearly designed to attract custom for a wide variety of services that she offers. Apart from the advertising blurb on the link page, I couldn't find any more details.
I tried Amazon both in the US and the UK to see what reviews there were. There were none on both sites. The US site listed a 1972 copy, the UK site a 1977 copy, so I guess that either it hasn't been updated since 1977 or updated copies can only be bought through her website.
A 40 year old book presents problems for a learner. Parts of it may well be fine but other parts may give views that are no longer held. All branches of Astrology have moved on since then and indeed there's much debate in the Astrological Community over its state at the moment.
But the biggest possible problem, is hinted at by the short summary. It gives an easy way to calculate your chart. Now that claim may or may not be true but it leads me to speculate. In 1977 there were hardly any home computers (and I think that's an overstatement) and no internet. If you wanted to read your own chart you needed to calculate it - and even calculators were in their infancy. So you ended up with pen, paper, some tables and a lot of maths. Introductory text books had to start with the calculations because you can't interpret a chart unless you first calculate it.
Most people who just wanted a reading had to pay an Astrologer to do the calculations for them as well as the interpretation.
Now you can simply go to astro.com and enter your data (time of birth, place of birth and date of birth) and in seconds you have your chart and can proceed to try and interpret it.
Many Introductory books now ignore the calculations and concentrate on the signs, often with a bias towards relationships, because that is one of the main areas of interest for the beginner. It's certainly the main area of interest for those who ask questions in the horary threads
Some of them may simply need you to know what your Sun Sign is and virtually no more. If you are serious in terms of learning you want more from your introductory text.
What you need is a book that covers the following:
The planets and their natures (from which their meanings are derived)
The Signs of the Zodiac and their natures. Modern Astrology puts more weight on the signs themselves than Traditional Astrology does.
The houses of the horoscope (strictly speaking the houses of an Astrological chart because the horoscope is the Ascendant of the chart)
I've listed them in the order in which they are usually covered but it's the planets and houses that are the important elements for moving beyond the beginners stage.
A good introductory text should tell you in fairly simple terms how a chart is constructed, or at least what it represents in terms of space and time. However, doing your own chart is no longer necessary at the beginners' level. Later on you can explore that for yourself because ideally every intermediate student should learn how to construct a chart by using tables and a calculator, It does help a lot for your development as an Astrologer.

Gives a list of possible introductory texts, but it isn't exclusive.
Sadly Astrology today is diverse and this means that no book gives the perfect introduction. The dominant approach over the last 50 - 60 years has been from a psychological (mainly Jungian) starting point. However in the last ten to twenty years, there has been a lot of variations and criticisms. They may not be important at the beginners' level but you should be aware of them. Two major but contrasting innovations are worth being aware of. The first is the use of Asteroids, the second is the interest in the traditional approaches to Astrology.
These aren't necessarily incompatible The Astrologer, Demetra George started the Asteroid interest going with her book
Asteroid Goddesses in the mid 90's (1995 I think) but then she discovered Hellenistic Astrology and ended up trying to synthesise Modern and Ancient approaches in
Astrology For The Authentic Self in 2008.
Again such books go beyond the beginner's level but are well worth reading when you get time.
This forum is also a good place to ask questions when you are learning. One area that completes the beginners' phase is to learn something about aspects. However this isn't an easy section as Modern Astrology has invented a myriad of these and the more bodies (such as adding the asteroids to the planets) makes the area a graveyard of beginners.
My advice would be to keep the bodies to a minimum (say just planets). Keep to the four angles of the chart (Ascendant, MC, Descendant and IC) as your only other points.
Finally keep to the major aspects (Conjunction, Opposition, Square, Trine and Sextile). Leave out the minor aspects and the so called harmonics.
I still keep to planets (the classical seven) and the major aspects and find no need for the others. So you can practice effective Astrology without having to understand and integrate a whole host of bodies and relationships. Of course as you pass through intermediate into advance stages, you may want to do just that but don't try and run before you can walk.
